摘要:
Rifamycin antibiotic derivatives of formulae (I) and (Ia) bearing at the position 36 a substituent selected from (C.sub.1 -C.sub.8)alkyl, halo, hydroxy, (C.sub.1 -C.sub.4)acyloxy, (C.sub.1-C.sub.4)alkoxy, (C.sub.1 -C.sub.4)alkylthio, (C.sub.1 -C.sub.4)alkylamino, di(C.sub.1-C.sub.4)alkylamino and substituted 4-oxo-3-pyridinyl carbonyloxy of formula (1) obtained by reacting rifamycin with suitably substituted malonic acid. The compounds of the invention are antimicrobial agents mainly active against gram positive bacteria and fastidious gram negative bacteria showing the considerable antimicrobial activity against the rifamypicin resistant microbial strains.
摘要:

摘要:
The present invention is directed to a new antibiotic substance denominated antibiotic A 42867 pseudoaglycon, a pharmaceutically acceptable salt thereof, a process for its preparation from antibiotic A 42867 and pharmaceutical compositions containing the new substance of the invention.
摘要:
Solid phase immunoassay for detecting specific inhibitors of proteolytic enzymes in biological fluids, which comprises: a) contacting a tubulin peptide covalently linked to a support with a solution containing a proteolytic activity together with a protease inhibitor, b) detecting the inhibitor activity against the selected proteases by contacting the support with a solution containing a labelled monoclonal antibody which specifically recognises the free end of the tubulin peptide linked to the support.
摘要:
The present invention concerns the use of puberulic or puberulonic acid as inhibitors of the enzyme iositol monophosphatase (EC 3.1.3.25) and thus useful in the treatment of manic or depressive symptoms.
摘要:
The present invention is directed to new antibiotic substances denominated antibiotic GE 2270 factors B.sub.1, B.sub.2, C.sub.1, C.sub.2, D.sub.1, D.sub.2, E and T, the addition salts thereof, the pharmaceutical compositions thereof and their use as medicaments, particularly in the treatment of infectious diseases involving microorganisms susceptible to them and their use as animal growth promoters.
摘要:
The present invention concerns novel compounds obtained by fermenting a microorganism of the genus Memnonoiella or Stachybotrys, which compounds are inhibitors of the enzyme inositol monophosphatase (EC 3.1.3.25). The present invention also relates to the use of these novel compounds in treating manic depression and pharmaceutical formulations comprising said compounds as active ingredient; a further object is the use of these compounds in an analytical method for detecting inositol monophosphatase.
